Green Island, Great Barrier Reef: Is It Worth Visiting?

What is Green Island like?

Think less desert island and more a tiny tropical island with a lot packed onto it. You’ll find:

• sandy beaches
• fringing coral reef
• tropical vegetation and rainforest
• a boardwalk
• a jetty
• swimming areas
• snorkelling
• glass-bottom boats
• diving
• places to eat
• toilets and showers
• beach equipment hire
• an island resort
• other optional reef activities

It is developed enough to make the day easy without feeling like a city attraction. Queensland Parks says the national park day-use area has toilets, picnic tables, drinking water and wheelchair-accessible facilities, and that the jetty, boardwalk and resort paths suit wheelchairs and prams, though you may need help in places. That practicality is one of the island’s biggest strengths.

How far is Green Island from Cairns?

About 27 km offshore. The fast catamarans usually take 45 to 50 minutes, depending on the sea, which makes Green Island much easier to reach than the outer reef, roughly 1.5 hours away. If you are worried about a long time at sea, that alone can be the reason to choose it. Our guide to how far the reef is from Cairns has the times for every kind of trip.

How do you get to Green Island from Cairns?

Most visitors take a ferry from the Reef Fleet Terminal in Cairns. There are two main operators.

1. Great Adventures

Great Adventures’ catamarans leave Cairns at 8:30am and 10:30am and leave Green Island at 2:30pm and 4:30pm, and each crossing takes about 45 minutes. Take the first boat out and the last one back and you get up to seven hours on the island. The Great Adventures Green Island cruise (our breakdown) starts at $79, with a choice of cruise only, a glass-bottom boat tour or snorkel gear, a marine biologist reef talk and use of the island pool kept for Great Adventures guests. It is rated 4.4 from more than 1,900 reviews.

2. Big Cat Green Island Reef Cruises

Big Cat sells full days, half days and ferry-only fares. Big Cat says its standard full day gives up to about 5½ hours on the island, and its half days about 2 hours 15 minutes. The Big Cat full-day Green Island cruise (our breakdown) starts at $77 for a day of about eight hours door to door, with snorkel gear or a glass-bottom boat tour in the fare, rated 4.5 from more than 1,700 reviews. For a first visit, take the longest stay on the island your plans allow.

Half day or full day: how long do you need on Green Island?

This is one of the easier decisions.

Half day

A half day suits you if:

• you’re short on time
• you mainly want to see the island
• you want one snorkel or one glass-bottom boat ride
• you’re fitting Green Island around something else in Cairns

About two hours on the island is enough to walk off the jetty, snorkel or take the glass-bottom boat, have a quick look round and get back to the ferry, with little time to spare. The Big Cat half-day afternoon cruise gives you about 2 hours 15 minutes on the island from $77, rated 4.3 from more than 450 reviews, and the Big Cat half-day morning cruise costs the same, rated 4.1 from more than 450 reviews.

Full day

For most people, a full day is the better choice. A longer stay lets you:

• snorkel more than once
• wait for a better tide
• walk around the island
• have lunch without rushing
• spend time on the beach
• take the glass-bottom boat
• add a guided snorkel or another activity
• stop looking at the clock

Green Island works best as an island day, not an attraction you have two hours to get through. If it is your main reef day, skip the half day unless your plans leave no other choice. If you would rather not get up early, the Big Cat later-start full day leaves Cairns at 11am, from $77, rated 4.3 from 273 reviews.

Is the snorkelling good at Green Island?

Yes, but this is where your expectations need setting. Its big advantage is that you snorkel from the beach. You don’t climb down from a large boat into open water: you walk onto the sand, put on your mask and fins, wade in gradually and come back to shore whenever you want. That makes Green Island especially approachable for:

• first-time snorkellers
• families
• less confident swimmers
• anyone who dislikes jumping off boats

The island is ringed by reef and seagrass, and Queensland Parks notes that the seagrass beds draw turtles to the waters around it. Tourism Queensland says the reef around the island holds more than 190 kinds of hard coral and 100 kinds of soft coral. That doesn’t mean every metre of shoreline looks like a wildlife documentary.

Is Green Island snorkelling as good as the Outer Reef?

Usually the outer reef has the edge for dedicated snorkelling. Green Island’s strengths are:

• easy access
• entry from the beach
• shallow water
• flexibility
• turtles and seagrass
• a reef and a beach together

The outer reef’s strengths are usually:

• bigger reef structures
• distance from the coast and its river water
• deeper coral gardens and reef edges
• a day built for snorkelling and diving
• sites chosen for the day’s underwater conditions

Tourism Queensland describes outer reef day trips from Cairns as visits to offshore coral gardens, normally at one or two sites chosen for snorkelling and diving. So which has the better snorkelling? The outer reef for what you see underwater; Green Island for ease and variety.

Green Island vs Outer Reef

Which one, for whom

• A couple who mainly want to snorkel: the outer reef.
• Parents with young children: Green Island, or an outer reef pontoon.
• One swimmer and one non-swimmer: Green Island works very well.
• Someone nervous about boats: Green Island.
• A certified diver: the outer reef.
• Someone dreaming of a tropical beach: Green Island.

What can you see while snorkelling at Green Island?

You may see:

• green sea turtles
• tropical reef fish
• parrotfish
• butterflyfish
• damselfish
• wrasse
• hard corals
• soft corals
• giant clams
• rays
• sea cucumbers
• other reef invertebrates

The mix of reef and seagrass matters. Some of the wildlife is not sitting among bright coral heads; turtles, for example, may be feeding over the seagrass. Queensland Parks highlights the turtles around Green Island and describes the reef as rich in fish, corals and invertebrates. As always, no sighting is guaranteed.

Where should you snorkel on Green Island?

Don’t rely on an old blog telling you to walk 100 m left of the jetty. Tides, wind and water depth change, so the best place to get in on your day may not be the spot someone described six months ago. Queensland Parks asks visitors to check with the lifeguard for safe snorkelling spots and says the patrolled beach is the safest place to swim. The sensible order is:

1. arrive
2. look at the conditions
3. ask where the snorkelling is best that day
4. get in from the recommended area

That beats pretending one point on a map is the best snorkelling spot for everyone.

Does the tide matter at Green Island?

Yes, more than many visitors expect. Because the fringing reef is shallow, a very low tide makes some areas harder to reach. Queensland Parks recommends planning your swim and snorkel around high tide where you can, because getting in and out is easier, and the Green Island listings say the same: at low tide the coral can be a long swim out. That doesn’t mean you should skip the island on a low-tide day. It means that if snorkelling is the main reason you’re going, check the tide before you choose your ferry times.

Should you book a guided snorkel tour?

If you’re a confident snorkeller who wants to see more than the easy reef off the beach, yes, it can be worth it. Big Cat runs a guided Snorkel Safari, which Big Cat describes as about 50 minutes, where a small boat takes capable swimmers to reef further from the usual entry points; it is meant for competent swimmers and snorkellers. That gives you three levels to choose from.

Level 1 — casual snorkelling

Walk in from the beach and explore on your own.

Level 2 — guided shore snorkelling

Good if you want help spotting wildlife or building confidence.

Level 3 — boat-access snorkel safari

Better for confident snorkellers who want reef away from the busiest entry points. If you’re choosing Green Island but still care a lot about the snorkelling, this is the one to look at.

Can you snorkel if you’re not a strong swimmer?

You don’t need to be an athlete, but take the sea seriously. The gear on offer can include:

• flotation vests
• Lycra suits
• prescription masks
• a standard mask, snorkel and fins

Big Cat includes flotation vests and Lycra suits with some snorkel hire, and Great Adventures has buoyancy aids through its dive shop. Queensland Parks recommends swimming with someone else and wearing a flotation vest or buoyancy aid. If you can’t swim at all, though, don’t treat snorkelling as something you have to do. Green Island has better dry options than most reef trips. Our guide for non-swimmers covers them.

Is Green Island good for non-swimmers?

Yes, and it is one of the island’s biggest strengths. A non-swimmer can:

• walk on the beach
• explore the rainforest boardwalk
• take a glass-bottom boat
• look for fish and turtles from the jetty
• relax on the sand
• have lunch
• use the island facilities

That makes Green Island especially good for families, or couples where only one person wants to snorkel.

Are glass-bottom boats worth it?

For non-swimmers, absolutely. For snorkellers, they can still be worthwhile, especially if one is already in your fare. Big Cat says its glass-bottom boat trip lasts about 30 minutes and shows you the reef and fish without getting wet. If you are travelling with grandparents, very young children, non-swimmers or anyone uneasy in open water, it is the simplest way to make sure everyone sees something below the surface.

Snorkel hire or glass-bottom boat: which should you choose?

Several Green Island fares let you pick one or the other.

Choose snorkel equipment if:

• you’re comfortable swimming
• you want to explore on your own
• you expect to spend a lot of time in the water
• you’ve come mainly for the reef

Choose the glass-bottom boat if:

• you’re a non-swimmer
• you’re travelling with very small children
• you only plan a casual swim
• you have your own snorkel gear or plan to hire it separately

If your fare includes both

Even better. Great Adventures sells a Discovery fare with both snorkel gear and a glass-bottom boat. On GetYourGuide, the Great Adventures snorkel or glass-bottom boat day (our breakdown) starts at $109, rated 4.4 from more than 140 reviews; its listing is unclear on whether you get both or a choice, so check the option you book.

Can you scuba dive at Green Island?

Yes. Introductory and certified dives are both available on or around Green Island. But the advice from our scuba diving guide still stands: if diving is the reason you’re visiting the reef, look at outer reef dive boats first. Green Island diving makes sense when you are thinking “we want an island day, and I’d like to do a dive too”, not “I have one day in Cairns and want the best diving I can get”.

Certified divers need proof of certification, and introductory divers must meet Queensland’s medical and participation rules. The Big Cat Green Island day with diving costs $175, rated 4.9 but from only 10 reviews so far. For something in between, the Green Island and Seawalker helmet dive combo lets you walk on the sea floor wearing a helmet, no certificate needed, from age 12, for $203, rated 4.4 from 66 reviews.

What is there to do besides snorkelling?

More than you might expect.

Walk through the rainforest

Green Island is unusual because the coral cay carries tropical vegetation and rainforest, and it is small enough that you won’t need hiking boots. Queensland Parks maps a 1.5 km beach circuit that takes about 45 minutes, though the beach walk should not be tried at high tide. There are accessible boardwalk sections too.

Walk the jetty

The jetty isn’t just where you arrive. Look down: the clear water and reef around it make the jetty a good place to spot fish, and sometimes turtles, without getting in the sea.

Swim

There is a patrolled swimming area on the north side of the island. For anyone who wants a tropical swim without snorkelling, Green Island is far easier than an offshore reef boat. Great Adventures guests can also use the island pool.

Relax on the beach

It sounds obvious, but it is the big difference. On an outer reef boat, when you finish snorkelling you go back to the boat or the platform. On Green Island you lie on the sand, and sometimes that is exactly what people want from a Cairns holiday.

Hire beach equipment

Depending on what’s available, you can hire:

• umbrellas
• sun lounges
• towels
• non-motorised watersports gear

Queensland Parks confirms equipment hire around the day-use area.

Visit Marineland Melanesia

There is also a crocodile and wildlife attraction on the island, which Queensland Parks lists among the island’s visitor attractions. Treat it as an optional extra, not a reason to choose Green Island. The island and the reef are the point.

Can you combine Green Island and the Outer Reef?

Yes, and for some visitors it is the best answer. The Great Adventures Green Island and Moore Reef combo (our breakdown) runs roughly like this, by Great Adventures’ own timetable:

• 8:30am: leave Cairns
• 9:15am: arrive at Green Island
• 11:20am: leave Green Island
• 12:30pm: arrive at the outer reef
• 3:30pm: leave the outer reef
• 5:30pm: back in Cairns

That gives about two hours on Green Island, with snorkel gear, then three hours at the Moore Reef platform with snorkelling, a semi-submarine tour, an underwater observatory and a buffet lunch with prawns. It costs $219, rated 4.6 from 97 reviews.

Is the combination worth it?

Yes, if:

• you have only one reef day
• you want to try the island and the outer reef
• you don’t mind a busy schedule
• you don’t mind more time on the boat

No, if:

• you hate rushing
• you want a relaxed beach day
• keen snorkelling is your priority
• you have time for two separate trips

It is a sampler, not the fullest version of either.

Green Island only vs Green Island + Outer Reef

If you have two days free, keep them separate: Green Island properly on one, an outer reef trip on the other. If you have one day and can’t choose, the combination is a clever compromise.

How much does Green Island cost?

Treat these as examples for the day we checked, not fixed rates. They are GetYourGuide’s from-prices per person in US dollars:

On their own sites, Great Adventures sells a ferry-only fare, an Eco Adventure fare with snorkel gear or a glass-bottom boat, and a Discovery fare with both, and Big Cat sells ferry-only and snorkel-or-boat fares. Big Cat says its rates include the Environmental Management Charge, jetty tax and GST. Children under four travel free with both operators, according to their websites, but still need to be on the booking.

Which Green Island ticket is best value?

For most first-time visitors, skip the ferry-only fare unless:

• you have your own snorkel gear
• you’re mainly going for the beach
• you know exactly which extras you’ll buy on the island

The small step up to a fare with snorkel gear or a glass-bottom boat usually makes more sense.

Picks by traveller

• Cheapest sensible trip: a full-day fare with snorkel hire, such as the Big Cat full day.
• Best for non-swimmers: a full-day fare with the glass-bottom boat.
• One snorkeller and one non-snorkeller: a fare with both.
• Torn between the island and the reef: the Green Island and Moore Reef combo.

Is Green Island good for families?

Very much so. Families are one of the groups for whom Green Island beats a dive-focused outer reef boat, because children can move between the beach, swimming, snorkelling, walking, the glass-bottom boat, food, shade and dry land. A child who gets tired of snorkelling doesn’t leave the whole family stuck on a boat for four more hours. That flexibility is worth a lot.

Is Green Island good with toddlers?

It can be. In its favour:

• a short crossing compared with the outer reef
• the beach
• toilets
• food
• shade
• paths and boardwalk that take a pram
• things to do out of the water

The caution is that it is still a tropical marine setting. Watch small children closely around the water, the sun, the heat, the jetty and the wildlife.

Is Green Island good for older travellers?

Yes, especially compared with trips where you have to get in and out of the water from a boat. You can do as much or as little as you like. Someone who doesn’t snorkel can still enjoy the ferry ride, the island, the glass-bottom boat, the accessible paths, lunch and the beach. Queensland Parks says the jetty, boardwalk and resort paths take wheelchairs, though help may be needed. If mobility is limited, check boarding arrangements with the operator before booking.

What is the best time of year to visit Green Island?

The boats run all year. Broadly:

May to October

Expect lower humidity, mostly drier weather, cooler water and a busy travel season.

November to April

Expect warmer water, higher humidity, more rain, stinger suits and the odd tropical weather disruption.

There’s no blanket reason to avoid Green Island in summer, but the weather shapes this trip more than many sightseeing days. A calm, bright day makes the shallow water look spectacular; a windy grey one gives a very different first impression. Our best time to visit guide goes month by month.

What about marine stingers?

Marine stingers live in tropical waters, mostly in the warmer months; around Cairns the season runs roughly from November to May. Queensland Parks advises wearing a stinger suit when you swim or snorkel, for sun protection as well as against jellyfish, and the operators make Lycra suits available. Follow the island’s advice on the day instead of trusting a “safe” month.

Is Green Island crowded?

It can be. That is the trade-off for being one of the easiest reef islands to reach. Green Island Resort says most day visitors are on the island between about 9:30am and 4pm. It feels busiest around the ferry arrivals, the jetty, the main facilities and the popular entry points to the water, but people spread out once they arrive. If crowds bother you, Green Island won’t match the untouched-island picture in your head. It is an easy, established day-trip island, which is both its weakness and its strength.

Can you stay overnight?

Yes. Green Island Resort lets you stay on after the day visitors leave, which changes the island completely. The resort says day visitors are generally gone by late afternoon, leaving overnight guests a much quieter island. An overnight stay suits you if you want:

• quieter beaches
• early mornings on the island
• the sunset
• less of a day-trip atmosphere
• a slower trip for a honeymoon or a couple

For most Cairns visitors, though, a full day on the ferry is enough.

Can you eat on Green Island?

Yes, so you don’t need a packed lunch unless you want one. There are takeaway places and restaurants, and Green Island Resort lists the Canopy Grill for casual daytime food among its options. Food on an offshore tourist island is rarely the cheapest meal of a Queensland holiday, though, so families watching the budget may want to bring snacks. Neither Great Adventures fare includes lunch; some Big Cat options add a buffet.

What should you bring?

Bring:

• swimwear
• a towel
• a hat
• sunscreen
• sunglasses
• a water bottle
• a dry change of clothes
• a waterproof phone pouch or camera
• sandals or shoes for walking
• seasickness tablets if you need them
• a card or cash for food and extras

If snorkel gear comes with your fare, there’s little point carrying bulky fins unless you strongly prefer your own.

Do you need reef shoes?

Not necessarily. The usual entry points are managed for visitors, but this isn’t a soft sandy pool: expect coral fragments, shells and uneven reef rubble. Follow local advice on where to get in. Above all, don’t stand on living coral. Queensland Parks asks visitors to rest only on sand, never on coral or coral rock.

Can you fly a drone on Green Island?

No, not casually. Great Adventures says drones are not allowed because Green Island is a sensitive national park and marine park area with helicopters operating, and its listings repeat the rule. Leave the drone at the hotel unless you have specific permission.

Is Green Island better than Fitzroy Island?

They overlap, but they aren’t straight substitutes.

Green Island

Strongest for:

• the classic sandy tropical island look
• easy snorkelling
• glass-bottom boats
• reef activity packages
• mixed groups
• very short walks

Fitzroy Island

Strongest for:

• the feel of a bigger island
• hiking
• dramatic beaches
• a more rugged day
• exploring the island as well as snorkelling

The Fitzroy Island full-day trip (our breakdown) starts at $76 with up to seven hours on a granite island with walking tracks, rated 4.5 from more than 1,900 reviews. If you can’t choose, the two islands in one day trip visits both for $138, though it is rated lower, 4.0 from more than 180 reviews. Our Fitzroy Island tours page has the ferries.

Is Green Island worth visiting if you’ve already booked an Outer Reef trip?

That depends on how many days you have.

Yes, if:

• you like beaches
• you want an island day
• you have children
• you want an easy day after a full-on reef cruise
• you enjoy snorkelling enough to go again

Probably not, if:

• you only have two days in Cairns
• you mainly care about what the reef looks like underwater
• you’d rather spend the day on the Daintree, Kuranda or something completely different

Green Island and the outer reef overlap, but they don’t feel the same. Doing both isn’t pointless; it just isn’t essential.

Is Green Island worth visiting if you cannot snorkel?

Yes, and that is where it compares well with the more water-focused reef trips. You can still take a glass-bottom boat, explore the island, swim in the shallow patrolled area if you’re comfortable, walk through the rainforest, sit on the beach and watch for marine life from the jetty. If you have no interest in the reef or beaches at all, though, Green Island shouldn’t be high on your Cairns list.

Is Green Island touristy?

Yes, and that isn’t automatically bad. Green Island has regular ferry arrivals, restaurants, organised activities, snorkel hire, resort facilities and commercial attractions. It is not a wild island with nobody else around. But the same setup gives you lifeguards, toilets, showers, food, accessible paths, equipment, organised reef trips and frequent ferries. The real question is whether you value convenience more than remoteness.

Is Green Island overrated?

No, but it is sometimes booked for the wrong reason. Someone expecting the best coral snorkelling available from Cairns may come home wondering why they didn’t go to the outer reef. Someone expecting an easy tropical island where they can snorkel, swim, walk, sit on a beach and still be back in Cairns for dinner will see straight away why Green Island is so popular. The island is good; it just needs to be booked for what it is.

Who should book Green Island?

A family

The island offers far more options than a snorkel-only boat.

A first-time Great Barrier Reef visitor

It is easy to get to and simple to enjoy.

A nervous snorkeller

Walking in from the beach feels far less daunting than jumping off a boat.

Travelling with non-swimmers

Glass-bottom boats and things to do on land include everyone.

Looking for a tropical beach

This is one of the main reasons to choose it over an outer reef pontoon.

Short on travel tolerance

The crossing is short.

Who should skip Green Island?

A serious snorkeller with only one Reef day

Go to the outer reef.

A certified diver

Book a dive-focused offshore boat.

Looking for an untouched island

Green Island is busy and developed.

Mainly interested in hiking

Look at Fitzroy Island, or a rainforest day on the mainland.

Set on seeing the “best coral”

Don’t assume the easiest access means the best snorkelling.

A good first Green Island day

This is how we would plan a first visit.

8:30–9:00am — leave Cairns

Take an early ferry; the morning gives you more room for everything after it.

Around 9:15–10:00am — arrive and orient yourself

Before you drop your bag on the nearest patch of sand, check the tide, the wind, the swimming flags, where the snorkelling is best today and the times of anything you have booked.

Morning — snorkel

Do it while you’re fresh. If the tide and conditions are good, make the reef your first priority.

Late morning — walk the island

Follow the boardwalk and whichever beach sections the tide allows.

Lunch

Take a proper break.

Early afternoon — glass-bottom boat or guided snorkel

A second way of seeing the reef.

Later afternoon — beach

Stop trying to optimise your holiday and lie down. You’re on a coral cay in the Great Barrier Reef.

Late ferry back

Unless something is waiting for you in Cairns, don’t rush back on the first boat.

Final verdict: Is Green Island worth it?

Yes, for the right traveller. Green Island’s greatest strength isn’t that it has the most spectacular snorkelling from Cairns. It is that almost everyone finds something to enjoy there. You snorkel straight off the beach, a non-swimmer takes the glass-bottom boat, children climb out when they get tired, and you can walk through the rainforest, eat lunch, swim, sit under a tree and spend the afternoon on the sand, all less than an hour from Cairns.

If you’re choosing purely for coral and what you see underwater, book the outer reef. If you want a full tropical island day with the Great Barrier Reef all around it, Green Island is one of the easiest recommendations in Cairns.

Frequently asked questions

Is Green Island really on the Great Barrier Reef?

Yes. Green Island is a coral cay inside the Great Barrier Reef World Heritage Area, about 27 km off Cairns.

How long is the ferry from Cairns to Green Island?

About 45 to 50 minutes, depending on the boat and the sea.

Can you snorkel directly from Green Island?

Yes. Snorkelling straight off the beach is one of the island’s biggest advantages.

Is Green Island good for snorkelling?

Yes, especially for beginners and anyone who values easy access from the shore. Keen snorkellers may prefer an outer reef trip or Big Cat’s guided snorkel safari by boat.

Is Green Island or the Outer Reef better?

Green Island is better for a beach, rainforest and reef together. The outer reef is usually better if snorkelling or diving is your main priority.

How long should you spend on Green Island?

A half day is possible, but take a full day if Green Island is your main excursion.

Can you see turtles at Green Island?

Yes, turtles feed around the island and its seagrass, though sightings are never guaranteed.

Can non-swimmers visit Green Island?

Yes. Glass-bottom boats, the beach, the boardwalks and other dry activities make it one of the best Cairns reef trips for non-swimmers.

Is Green Island good for children?

Yes. The beach, swimming, snorkelling, toilets, food and things to do on land make it very family-friendly.

Can you scuba dive at Green Island?

Yes. Introductory and certified dives are available, though keen divers should compare outer reef dive boats too.

Can you visit Green Island and the Outer Reef on the same day?

Yes. The Great Adventures combo gives you about two hours on Green Island and then three hours at its Moore Reef platform.

Does low tide affect snorkelling?

It can. Very low tides make getting in and the shallow reef less convenient, and Queensland Parks recommends high tide where possible.

Is there food on Green Island?

Yes. The island has cafés, takeaway food and restaurants.

Can you stay overnight?

Yes. Green Island Resort has rooms, and the island becomes much quieter once most day visitors leave.
